How To Fix Samsung Galaxy S9 App Has No Sound Notification

Problem: Hi, I have a Samsung Galaxy S9. It has always worked fine so far, and I have so much important info on there I have been reluctant to install the latest Software update , that’s says the new inclusion is the GDPR update. I’ve not updated as last time I did the software update the phone crashed and it had to be sent off to factory reset, as I wasn’t even able to switch it off. BUT recently I installed a home surveillance camera which uses CLoud Edge APP and when motion or sound is detected, it is supposed to send an alarm notification to my mobile. Now , I am actually getting a notification message on my lock screen, but it isn’t making a sound alarm sound along with the notification, is not lighting up, nor vibrating, so I have to be looking at my phone to see that there is motion detected to see there is a notification. Which defeats the object. I’ve tried to resolve by messaging the seller, but to no avail. Everything seems to be in place on my settings. Would you know if this problem could be because of the Software being out of date please ? or would you be able to help me with any other checks I need to do.

Solution: Before performing any troubleshooting steps on this device it is always best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.

Turn on the app notification setting

The first thing you will want to do in this case is to check and make sure that the notification switch of app in particular is turned on.

  • Slide your finger downward from the top of the screen.
  • Tap the Settings icon
  • Tap Notifications
  • Tap the indicator next to the required app to turn on the function.
  • Tap the Home key to return to the Home screen.

Check if the issue still occurs.

Perform a soft reset

The next thing that you will need to do in this particular case is a soft reset. This will usually fix issues caused by minor software glitches as it will refresh the phone software. This is also called as a simulated battery pull as it disconnects the phone from the battery.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Check if the issue still occurs.

Wipe the cache partition of the phone

There are cases when the cached data that the phone stores in its partition can become corrupted. Once this happens certain issues can occur on the device. To eliminate the possibility of this issue causing the problem you should wipe the cache partition of the phone.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the Android logo displays, release all three keys.
  • An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  • Press the Volume down key several times to highlight wipe cache partition.
  • Press Power key to select.
  • Press the Volume down key to highlight yes, them and press the Power key to select.
  • When the wipe cache partition is complete, Reboot system now is highlighted.
  • Press the Power key to restart the device.

Perform a factory reset

One last troubleshooting step to consider is a factory reset. This will revert the phone back to its original factory condition. Make sure to backup your phone data before performing this step.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

Once the reset is complete download the app again then check if the issue still occurs. If it does and you are only having a problem with this particular app then you should contact the app developer regarding this issue as this might already be caused by a bug in the app itself which should be fixed by an update.
